AUDIT AND RISK RANKING USING FUZZY LOGIC
Perception and perspective are two non-quantitative, subjective human characteristics that are commonly used when auditing Environmental, Health & Safety (EH&S) and Environmental Management System (EMS) programs. As such, it is a major challenge to develop the systems needed to assess risk in the mostly non-quantitative and subjective world of environmental management. It is an even larger challenge to communicate this risk to stakeholders. Given the imprecise methods currently available to rank this risk, there is a fundamental need to formalize human judgment and perception. In this paper, we discuss an approach for using “fuzzy logic” to rank risk. Fuzzy logic makes it possible to model the descriptive and simplistic measures often used in audit reports, yet produces auditing results with greater company-wide consistency and control.
